Steam-condenser



TED sTATEs PATENT oEEioE.

JAS. T. KING, OF NEW YORK, N. Y.

STEAM-CONDENSER.

'In Specification of Letters Patent No. 14,244, dated February 12, 1856.

To all whom t may concern.' l

Be it known that I, JAMES T. KING, of New York, in the county and State of New York, have invented a new and Improved Steam-Condensing Apparatus; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure I represents a vertical section of the apparatus, and Fig. II a horizontal section of the same.

The nat-ure of my invention consists in condensing steam by causing it to come directly in cont-act with the surface of water, and not allowing the uncondensed steam to escape, except through the water, by the application of a steamtight vertical partition, of any desirable depth from the top of a water-tank, in such a manner,that the steam coming in contact with the surface of the water on one side of the partition will be condensed until the water becomes heated to boiling point, when the pressure act-ing upon the water will cause it to fall, and rise in the opposite side of the partition, until the first shall reach the bottom of said partition, when the steam passes up through the water, and escapes into the open air or into another similar tank or tanks, thereby saving all the condensed w-ater and governing the pressure by the weight of water, without the noise occasioned by letting the steam into a tank below the surface of the water.

A, is a tank made of iron or any other suitable material.

B, is the cover fitted tight upon the top of the tank and provided with a manhole or door C.

D, is a vert-ical plate attached to the cover, B, and to the sides of the tank A and made perfectly steamtight. tendsabout one third the distance down into the tank, dividing thereby said top part of the tank into two tight compartments.

E is a horizontal plate attached to the bottom of the plate D, of a size of about one third of the sectional area of the tank.

F is a waterpipe to supply the tank with water and provided with a ballcock, Gr, or

a valve acted upon by a fioat, so as to main- This plate, D, eX-

tain the water always at a certain height in the tank.

H is a pipe leading the steam to be condensed into the tank or cistern.

K is the escape pipe for the uncondensed steam to escape at, after the same has passed through the water. This pipe acts at the same time for the overfiow pipe to the tank.

L, is a pipe byAwhich the warm water can be drawn oft, to feed the boiler or for any other required purpose.

S, is a vacuum valve, situated on the cover, on that side of the partition, where the steam is admitted, to prevent the pressure of the air on the opposite side of said partition, forcing the water into the pipe, H, when the influx of steam ceases, and a partial vacuum is formed.

The operation of the apparatus is as follows: The tank is filled through the pipe F with water up to a certain height which will be regulated according to the position of the ballcock, G, which said height will then always be retained by the action of said ballcock. The steam being admitted through the pipe H into the top of the tank A above the water, will be condensed by coming into contact with the same, heating thereby 'the water to the boiling point nearly, when the steam will force the water on that side of the partition down to the bottom of the partition D and pass under the plate E to Y the other side, forcing its way through the water on the other side, when the still uncondensed steam ca-n escape through the pipe K, heating by its passage through the water, said water to boiling point.

What I claim as my invention and desire to secure by Letters Patent is- A condensing tank having a vertical pary tition, D, of any desirable depth, with the inlet steam pipe and a vacuum valve upon one side of the partition D above the water, and the escape steam pipe on the opposite side of said partition, so that the steam, before it can escape must by its pressure force the water down one side of the partition and pass up through the water in the other side substantially as described.

JAMES T. KING.
